Disposable Absorbent Package Opening Tab Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging for single disposable absorbent articles, such as diapers, is difficult to open due to their small size, tight packaging, and the use of vacuum-sealed materials, making it hard for users to grasp and open them, especially when compared to packages containing multiple items.
Innovation Solution
The development of packaging designs that include an opening element, such as a pull tab or opening tab, which extends beyond the seal to facilitate easy opening without separating the package into two unconnected pieces, allowing users to grasp and open the package conveniently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the package is made small and tightly packaged for portability and discretion, then portability and discretion are improved, but ease of opening deteriorates
Solution Approach 1:
The package is segmented into distinct functional zones: a sealed enclosure for the absorbent article and an opening element (tab or flap) that extends beyond the seal. This segmentation allows the opening element to be grasped and manipulated separately from the main package body, enabling easy opening despite the package's small overall size.
Solution Approach 2:
The opening element acts as an intermediary between the user's fingers and the sealed package. By providing a tab or flap that extends beyond the seal, it mediates the opening action, allowing users to pull or peel the package open without needing to grasp the entire small package, thus resolving the contradiction between small size and ease of opening.
2Volume of moving object
If vacuum-sealed materials are used for tight packaging, then portability is improved, but ease of opening deteriorates
Solution Approach 1:
The opening element is pre-configured to provide a starting point for opening the vacuum-sealed package. The tab or flap is positioned and shaped in advance to allow users to easily initiate the opening process by grasping this pre-designed element, overcoming the resistance of the vacuum-sealed materials without requiring excessive force.
Solution Approach 2:
The opening element has different local properties compared to the main package body. It may be made from material with different tear resistance, or designed with a specific geometry (such as a peelable flap) that facilitates opening. This local quality difference allows the opening area to be more compliant and easier to open while the rest of the package maintains its vacuum-sealed, compact form.
3Quantity of substance
If the package contains only a single disposable absorbent article, then portability is improved, but ease of opening deteriorates
Solution Approach 1:
The package structure is segmented to include an opening element that is distinct from the main sealed body. This segmentation compensates for the reduced size inherent in single-article packaging by providing a dedicated grasping and opening feature, making the smaller package just as easy to open as larger multi-article packages.
Solution Approach 2:
The opening tab or flap serves as an intermediary that bridges the gap between the user's hand and the small sealed package. It allows users to easily open the single-article package by providing a larger surface area to grasp, effectively mediating the interaction between the user and the compact package contents.
